Index: bin/nice.c 4.2BSD
Description:
Despite the claim in nice(1) that the number argument is the
amount by which ``the priority is incremented'', it is actually
presented to setpriority(2) as an *absolute* priority, not an
increment.
Repeat-By:
As an ordinary (non-super) user, type
nice -2 nice -1 date
nice will print
setpriority: Permission denied
Fix:
My fix was to use nice(3c) instead of the overkill of getpriority(2).
